Anti-ISL1 Antibody

The ISL LIM Homeobox 1 (ISL1) transcription factor plays essential roles in cardiac progenitor specification, motor neuron differentiation, and pancreatic islet cell development. This unconjugated rabbit polyclonal antibody from Antibodies.com targets ISL1 and is validated for Western blot and immunofluorescence workflows. Supplied as 100 µl of polyclonal antiserum raised in rabbit, the reagent shows reactivity with human, mouse, and rat samples, making it useful across developmental biology, neuroscience, and cardiology research programs. Because the antibody is unconjugated, investigators retain full flexibility to pair it with secondary reagents of their choice, including HRP-labeled, fluorophore-conjugated, or biotinylated detection systems, depending on the application. For Western blot, the reagent can be used to detect endogenous ISL1 protein in tissue lysates or cultured cell lines. For immunofluorescence, it enables visualization of ISL1 expression patterns in fixed cells and tissue sections. Store refrigerated and protect from light; avoid repeated freeze-thaw cycles to preserve reagent activity over the working shelf life.
